Show a room the whole day from one phone: a big screen shows every station side by side and follows what you do.
Demo mode, under On the day, is for showing a committee or a club night how the day works. The big screen shows every station side by side and follows what you do on your phone: the flash, the siren and the safety card all appear a moment later.
Reset for the next run puts it all back: every fleet held, everyone ashore, bands and sign-ins cleared, and the rehearsal's entries removed.
No bands to hand? Try it yourself runs the same stations with practice bands on the screen.
